Sourcing Guidance
EN6347QI is obsolete or discontinued. Source only with date-code, label, package and traceability checks, and validate the suggested replacement independently.
For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.
Manufacturer Documentation
Technical values were checked against Intel Enpirion documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
EN6347QI selection and design context
EN6347QI is cataloged as a DC-DC Converter in the EN6347 family. Its recorded function is 4 A integrated PowerSoC synchronous buck converter with integrated inductor. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Output Current: 4 A. Check steady-state, transient and thermal margin in the intended operating mode.
- Input Voltage: 2.5 V to 6.6 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Output Voltage: 0.75 V to VIN. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Topology: Synchronous buck PowerSoC. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this power device, confirm input range, output requirements, switching frequency, compensation, current limit, efficiency and thermal design. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for EN6347QI
The recorded package is 38-pin QFN, 4 mm × 7 mm, the temperature range is -40°C to +85°C, and the lifecycle status is Obsolete as of 2026-07-20. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
EN6347QI FAQ
What distinguishes EN6347QI within the EN6347 family?
EN6347QI is the exact orderable code for a 4 A integrated PowerSoC synchronous buck converter with integrated inductor in 38-pin QFN, 4 mm × 7 mm. Related EN6347 devices may change package, rating, interface option or qualification grade, so compare the manufacturer ordering table before substitution.
What package and footprint checks are required for EN6347QI?
